Abstract (en)
[origin: EP0817503A1] This invention realizes a decoding apparatus and a decoding method capable of minimizing degradation of the quality of images and sounds when a synchronous signal error occurs. The decoding apparatus includes a frame counter 11 for receiving a bit stream 101, a synchronous pattern detector 12, a data error check unit 13, a synchronous detector 14, and a frame error determination unit 15. A synchronous detection error occurrence signal 106 produced by the synchronous detector 14 is not output to an external error processing circuit but is directly transmitted to the frame error determination unit 15. Even when the timing of an output synchronous pattern detection signal 104 from the synchronous pattern detector 12 and the timing of an output frame position signal 102 from the frame counter 11 do not match each other and a frame synchronous abnormality occurs, if the data itself is normal, decoding processing is executed without performing any error correction processing. <IMAGE>
